The band is placed aroiind aforin of the vdesiired' shape, the top is laid 'upen the form to beflush with the upperedge" of the bzu chend the extended portion ofthestriii' ie folded over uponthe top and ad heredthereto; thus uniting thetop and band. T he present invention embodies the manner of sup ortingand holding a box band during the process of securin a? strip thereto,

the band holder being" secured upon a clutch controlled power drivenshaft which is inouhtedon the strippinginachine, the holder being; inposition, to receive a strip supplied" from said machine and which iscoated with glue on one side. H

Referring to the accompanying drawings The improved box band holder A.is in the forin of a ring like dvicewhieh is' nade up of half roundsections 1 i and 2' which are formed on one" side with registering hinge45', the holders being of Varying diameters to suit boxta'nds 0f Varyingsizes, and about ajn' nch and a half wide. The inner fairies of'th'esectiohs'l an'dZ are formed with integral strengthening ribs 5, and theouts'i'cle srirface's of the" sections are formed 3:

meet-ere sections. v Upon the inner face i of efieli section: and on theopposite side thereof from the hinge,- is secured en angle pl'a te 7, byscrews's which pass through slots 9 in the"1nen1'ber 10 of the an leplate and into thesection. The members 11' of these angle ijla tes arenormally parallel and sep'zirz'ft'ed by e;- spa'oeflof about threequirters of an inch, and each of these nie nherslm's fornfed on itsinner side, a central longi-. tudinal rib of slight depth. The 'angleplates? are the sanievvidth as the ring sections and an integralbraeingWeb 13 con iiect s thfe two embers of each e fiat arm 14 extends acrossthe rear side (if the he'lder an d is seeiired it one end to hinge pinfl. The opposite e'ndof this iii-1n iefe'iinejcl with in aperture 15which also extends through z't'ho'ss 16 foi'ined on the i me pis s'efsthe ste or is'hanlli l'l' efru Cain or': spreader CL Thisgspridrcornfjrisesttbody portion 18 which ellib Iin, t'rzi'iisverse section andscrew 21 and thus holds the spreader against endwise movement.

A hand lever 22'is secured in the outer end of the spreader stem, andstop pins 23 and 24 project from the arm 14, which engage the set screw21, and

define the opening and closing movements of the spreader, as will beunderstood by reference to Fig. l. When the spreader is in the positionshown in Fig. 1, the band holder is closed,

and when the spreader is in the position shown in Fig. 4:,the band.holderis opened or expanded so as to fit tightly within and thus grip abox band placed thereon. A coil spring 25 is connected at one end to therib 5 of section 1 and at-its opposite end to the rib of section 2 andthis spring is under pulling tension so that the sections are spread orexpanded against the action of the spring and drawn toward each other bythe action of the spring. The end of the arm 14 which supports thespreader is heldto the band holder ley-the engagement of the flange 19,of the spreader with the ribs 12 on the angle plates 7 ,-and thisengagement not only relieves the strain onthe hinge connection butprevents any uneven movement of one section with respect to the othersection 1n either expanding or contracting the holder.

Afitting, comprising an internally threaded hub-26, having laterallyextending apertured ears 27 on one end, is secured to the I arm 14, byscrews 28 which extend through the arm and through the said ears, theaxis of'the hub 26 coinciding with the axis of the holder. The hub 26receives a threaded plug 29 which is rigidly mounted on the end I of apower driven shaft 30 which supports I and rotates the band hold andthis shaft forms a part of a stripping machinein commen use and whichtherefore forms no part of the present invention, enough only of thismachine being shown inFigures 6, land 8 to illustrate the manner inwhich the expansible holder is supported in the operation of applying astrip to a box band, it being understood that the improved holder isused. only in connection with the bands of round boxes and boxes havinga curved out line, such as the heart shaped box, other forms being usedfor the bands of rectangular boxes and others not having'curvedoutlines; such forms being connected to the shaft 30, in the samemanner'as the present expansible holder or as shown in Fig. 2.

A brief description of the strippingmachine will sufiice. The'shaft30,is supported in a bracket 31, on the outer end of an arm 32 mountedin a support 33 on'the end of a table 34. The shaft 30, carries a bevelgear 35, which meshes with a similar gear 36, on the outer end of ashaft 37 supported onthe arm 32. This shaft carries a bevel gear in ablmounted on the shaft and operatedyby,

a pusher 41 on the end of a rod 42 which is slid by means of a footlever 43, bell crank 44, and connection 15 between foot-lever and bellcrank. j

A stationary knifeAG is supported on a bracket 47 011 the upper end of astandard 48, mounted in a bracket 49 on the. end of the table 3 1. Aknife 50, is supported on a. bracket 51, pivotally connected to v thebracket 47, and operated by mechanism (not shown) to be swung upward andthen allowed to drop by gravity so that its knife 50. will 'coact withthe stationary knifedfi, to sever a strip passing between them, with ashearing .cut. The strip 52. passes over a glue distributor, (not shown)on the rear end ofthe table, and thence over suitable supports, as 53,and then between the cutting knives, and a portion of the strip ispassed around the box band, and severed from the main part of the strip,upon each rotation of the band, as will now appear.

In practice, the band to be stripped is placed around the holder so asto extend be yond the front edge thereof, as shown in Fig. 9, and thehand lever 22 is swung upward so as to turn the spreader from. the

position shown in Fig. 1, where, its long diameter is ona horizontalline, to the position shown in Fig. 4, when its long diameter is on avertical line, thereby spreading sections 1 and 20f the holderso thatthey fit tightly within the band and thus grip it; the angle platesbeing so adjusted, that the cam or spreader when in a vertical positionwill spread the sections .just far enoug'hto grip and hold the band, andnot far enough to cause them to part or break the band at the pointwhere its-two ends are taped or connected. In. this position of thespreader, the set screw'21, engages the stop pin 2% andprevents furtherinovement of the spreader as, will be understood by reference to Fig. 4.I I

The strip 52, which is glued on its under side, is about an inchwiderthan the band, so that itwill extend a half inch beyond each edgeof the band. The attendantthen attaches the free end of the strip to theband, as shown in Fig. 6, and depresses the footlever 43 by which theclutch 40 is coupled toare rotated, as above described and when theholder has made a complete rotation thereby causing the strip to adhereto the band, the knife 50 drops automatically and severs the strip andthe loose end of the strip encircling the band is pressed against theband by the attendant, this loose end being long enough to overlap theother end. The attendant then depresses the foot lever to again rotatethe holder, and as it rotates, the outer projecting edge portion of thestrip is tucked or folded in, manually against the inner face of theband, as shown by the dotted line X, Fig. 9, and the stripping operationis completed. The hand lever 22 is then turned to the position shown indotted lines Fig. 4, which permits the spring 25 to retract the sectionsof the holder and re lease the band, which is then removed and is readyto receive the top or bottom, as the case may be.

The ribs or projections 6 on the surface of the holder, not only actmore effectively to prevent slipping of the band on the holder, but theyalso prevent accidental contact of the glued strip with the surface ofthe holder; as it is apparent that if the surface of the holder wereperfectly smooth, contact of the glued strip therewith would result inthe strip adhering tightly to said surface, thereby causing annoyanceand loss of time.

Having described my invention, what I claim as new and desire to secureby Letters Patent is p 1.
